Androcentrism is a perspective or worldview that places male experiences, perspectives, and values at the center of societal norms, practices, and understanding, often marginalizing or ignoring female experiences and contributions. This bias can manifest in various fields, including literature, science, history, and culture, where male viewpoints are considered the standard or default. The term is derived from "andro," meaning male, and "centrism," indicating a focus or emphasis on a central point or idea.
Antipositivism is a philosophical stance that argues against the positivist approach, particularly in the social sciences. Positivism is the belief that the only authentic knowledge is that which is based on empirical evidence and that such knowledge can be acquired through scientific methods. Positivists typically assert that all meaningful statements can be verified through observation and experience.
The Philosophy of Science Association (PSA) is an organization that promotes scholarly research and discussion in the field of philosophy of science. It was founded in 1968 to foster communication and cooperation among those interested in philosophical issues related to the sciences. The PSA organizes conferences, publishes research, and supports educational initiatives in philosophy of science. The association serves as a platform for scholars to present their findings, engage in debates, and collaborate on projects.
"Physics envy" is a term often used in the social sciences and humanities to describe a phenomenon where scholars in these fields seek to adopt the methods, standards, and rigor of the natural sciences, particularly physics. This term expresses a certain admiration for the perceived precision, objectivity, and empirical validation found in physics, which some practitioners of the social sciences feel is lacking in their own disciplines.
Preformationism is a historical biological theory that existed before the discovery of modern genetics. It posited that organisms develop from pre-existing miniature versions of themselves, known as "homunculi." According to this view, all the traits of an organism were thought to be fully formed at the time of fertilization or were contained in the sperm or egg, and development was merely a process of growth and unfolding, rather than a process of complex development and differentiation from simpler forms.
Animal locomotion refers to the various ways in which animals move from one place to another. This movement can involve different body parts and mechanisms, depending on the species and its environment. The modes of locomotion are primarily categorized based on the anatomy and abilities of the animals, as well as the medium in which they move (such as land, water, or air). Common types of animal locomotion include: 1. **Walking and Running**: Most terrestrial animals use legs to walk or run.
Ciro Santilli's Stack Overflow contributions have, unsurprisingly, centered around the subjects he has worked with: systems programming and web development, and necessary tooling to get those done, such as Git, Python, Bash and Ubuntu.
His best answers are listed at: Section "The best articles by Ciro Santilli".
Stack Overflow has been the initial centerpiece of Ciro Santilli's campaign for freedom of speech in China, until Ciro noticed that GitHub might be potentially even more effective for it.
In Stack Overflow Ciro likes to:
  • answer important questions found through Google which he needs to solve an actual problem he has right now, and for which none of the existing answers satisfied him, and close duplicates.
  • monitor less known tags which very few people know a lot about and where the knowledge sharing desperately lacking, but in which Ciro specializes and therefore has some uncommon knowledge to share
In practice it also happens that Ciro:
When he gets an upvote on one of his more obscure answers, Ciro often re-reads it, and often finds improvements to be made and makes them.
He doesn't like to refresh the homepage looking for easy reputation on widely known subjects. See also: online forums that lock threads after some time are evil.
The result is that Ciro ends up getting relatively a lot of reputation without much work! The term passive income, much beloved by fake investment gurus, comes to mind. But now it's "passive reputation"! And it is useless! Yay!
For this reason, Necromancer is Ciro's favorite badge (get 5 upvotes on a question older than 60 days), and as of July 2019, he became the #1 user with the most of this badge. Announcement on Twitter.
The number two at the time was VonC (see also: Section "Epic Stack Overflow users"), who had about 16 times more answers than Ciro in total! From this query: data.stackexchange.com/stackoverflow/query/1072396?&Date=2019-07-01&UserId=895245 it can be seen that as of July 2019, 1216 out of his 1329 answers were answered 60 days after the questions and constitute potential necromancers! Compare that to VonC's 1643 potential necromancers out of 21767 answers!
VonC eventually took back the lead in 2022, dude's a machine!!! twitter.com/cirosantilli/status/1546389532014247936
Someone at Ciro's work once said something along:
The more patents a research project generates, the less actually working products it produces.
and this does ring true in Stack Overflow as well. When you are answering stuff, it means that you either didn't know, or that the information wasn't well available, and so your specific application is progressing slowly because of that. Once the generic prerequisites are well solved and answered, you will spend much more time on your business specific things rather than anything else that can be factored out across projects, and so you will get more "directly useful work" done, and less Stack Overflow answers. Of course, without the prior research in place, you can't get the final product done either.
In terms of per year reputation ranks, Ciro was in the top 100 in of the 2018 ranking with 38,710 reputation gained in that year: stackexchange.com/leagues/1/year/stackoverflow/2018-01-01?sort=reputationchange&page=4 (archive). He reached top 50 in 2022. Note that daily reputation is mostly capped to 200 per day, leading to a maximum 73000 per year. It is possible to overcome this limit either with bounties or accepts, and Ciro finds it amazing that some people actually break the 73k limit by far with accepts, e.g. Gordon Linoff reached 135k in 2018 (archive)! However, this is something that Ciro will never do, because it implies answering thousands and thousands of useless semi duplicate questions as fast as possible to get the accept. Ciro's reputation comes purely from upvotes on important question, and is therefore sustainable without any extra effort once achieved. Interestingly, Ciro appeared on top of the quarter SE rankings around 2019-11: web.archive.org/web/20191112100606/https://stackexchange.com/leagues but it was just a bug ;-)
There is no joy like answering an old question, and watching your better answer go up little by little until it dominates all others.
Stack Overflow reputation is of course, in itself, meaningless. People who contribute to popular subjects like web development will always have infinitely more reputation than those that contribute to low level subjects.
What happens on the specialized topics though is that you end up getting to know all the 5 users who contribute 95% of the content pretty soon as you study those subjects.
Like everything that man does, the majority of Ciro's answers are more or less superficial subjects that many people know but few have the patience to explain well, or they are updates to important questions reflecting upstream developments. But as long as they save 15 minutes from someone's life, that's fine.
There is great beauty when you are involved in a programming problem, and you suddenly remember: wait, I answered something related a few years ago! And especially so when you can go back and improve your old answer with new insight. This has great value, because when you were more newbie, you would have typed different words into Google Search than you would now. So by updating posts from when you were a newbie, you are helping other newbies more, as they are more likely to be also searching for those keywords. It is also very nice to have some head start on the answer's upvote count and not have to bootstrap yet another answer from 0 upvotes and have to go through all the competition!
For example, Ciro's most upvoted answer as of July 2019 is stackoverflow.com/questions/18875674/whats-the-difference-between-dependencies-devdependencies-and-peerdependencies/22004559#22004559 was written when he spent his first week playing with NodeJS (he was having a look at Overleaf, later merged into Overleaf, for education), which he didn't touch again for several years, and still hasn't "mastered" as of 2019! This did teach a concrete life lesson to Ciro however: it is impossible to know what is the most useful thing you can do right now very precisely. The best bet is to follow your instincts and do as much awesome stuff as you can, and then, with some luck, some of those attempts will cover an use case.
Ciro also derives great joy from his "media related answers" (3D graphics, audio, video), which are immensely fun to write, and sometimes borderline art, see answers such as those under "OpenGL" and "Media" under the best articles by Ciro Articles or even simpler answers such as:
There is something of greater value in perfectly presented technical knowledge, that goes beyond than simply getting something done. The pleasure of understanding and mastering something, and perhaps of the explanation itself. Sometimes when answering, Ciro feels like a tailor, where ASCII is his cloth. See also: Section "The art of programming", Section "Physics and the illusion of life".
Ciro's deep understanding of Stack Overflow mechanisms and its shortcomings also helped shape his ideas for: OurBigBook.com. So it is a bit funny to think that after all time Ciro spent on the website, he actually wants to destroy it and replace it with something better. There can be no innovation without some damage. It also led to Ciro's creation of Stack Overflow Vote Fraud Script.
After answering so many questions, he ended up converging to a more or less consistent style, which he formalized at:
Like any other style guide, this answer style guide, once fully incorporated and memorized, allows Ciro to write answers faster, without thinking about formatting issues.
Ciro also made a question title style guide: meta.stackexchange.com/questions/10647/how-do-i-write-a-good-title/311903#311903 but for some reason the Stack Overflow community prefers their semi-defined title meta-language to proper English. Go figure.
Ciro started contributing to Stack Overflow in 2012 when he was at École Polytechnique.
Like all things that end up shaping the course of one's life, Ciro started contributing without thinking too much about it.
His first answer was to the LaTeX question: Standalone diagrams with TikZ?, which reflects the fact that this happened while Ciro was reaching his Ciro Santilli's Open Source Enlightenment.
When he started contributing, Ciro was still a newbie. One early event he will never forget was when someone mentioned a "man page", and Ciro commented saying that there was a typo!
When Ciro reached 15 points and gained the ability to upvote, it felt like a major milestone, he even took a screenshot of the browser! 1k, 10k and 100k were also particularly exciting. When the 100k cup (archive) arrived in 2018, Ciro made a show-off Facebook post (archive). At some point though, your brain stops caring, and automatically filters out any upvotes you get except on the answers that you are really proud of and which don't yet have lots of upvotes. The last remaining useless gamed achievement that Ciro looked forward to was legendary (archive), and which he achieved on 2021-02-16.
From the start, Ciro's motivations for contributing to Stack Overflow have been a virtuous circle of:
  • save the world through free education
  • It feels especially amazing when people in the real world start taking note of you, and either close friends tell you straight out that you're a Stack Overflow God, or as you slowly and indirectly find out that less close know or came to you due to your amazing contributions.
It is also amazing when you start having a repertoire of answers, and as you are writing a new answer, you remember: "hey, the knowledge of that answer would be so welcome here", and so you link to the other answer as well at the perfect point. This somewhat achieves does what OurBigBook.com aims to do: for each small section of a tutorial, gather the best answers by multiple people.
Ciro feels that his Stack Overflow alter ego is kenorb.
Another one is Aaron Hall, who is also very high on the necromancer list, answers in Python which is a topic Ciro cares about, and states on his profile:
Follow me on Twitter and tell me what canonical questions you would like me to respond to!
so another necromancer.
Way to go.
Ciro also asks some questions on a ratio of about 1 question per 10 answers. But Ciro's questions tend to be about extremely niche that no one knows/cares about, and a high percentage of them ends up getting self answered either at asking time or after later research.
Some fun reactions to Ciro's Stack Overflow activity:
Planned obsolescence by Ciro Santilli 40 Updated 2025-07-16
The first time Ciro Santilli Googled this was when trying to repair his cell phone.
2019 cell phones are glued together with adhesive, which makes them impossible to repair them unless you have a heat gun, spend hours and hours learning and planning, and accept the risk of breaking the screen
If you take a phone less than 300 dollars to a repair shop in the first world, they will say: I've never repaired this crap, and likely for the price of the repair you should just buy a new one, and so to the trash goes the old one, polluting the planet, and in comes a new one, enriching the manufacturer further.
Ciro Santilli's dreams by Ciro Santilli 40 Updated 2025-07-16
Ciro Santilli's dreams almost all include the following aspect: Ciro is trying to do something mundane, like climbing a hill, walking across town, etc. but doing so it extremely difficult. The hill is too steep, he gets lost, and things which are easy to use in real life are impossibly hard to use in the dream.
So they are a bit like nightmares, but not that bad. Just really annoying and tiresome. Still, Ciro does enjoy o visiting the semi-real places those dreams bring him to, much for the same reasons he enjoys cycling.
Ciro attributes this type of dream to his occupation as a software engineer, because that's basically the feeling you get all day from it: why isn't this working!!! It is so basic!!!
www.tritoncycles.co.uk/urban-bikes-c4/hybrid-c30/trek-fx-3-equipped-urban-bike-2021-p39860/s102315 XL color Dnister Black. £675.00 plus £35.00 delivery. Disc breaks, 2x9 gears. Bought 2023 on a bit of a sale.
Specs upon buying:
Weight after bought measured differentially on bathroom scale: 13.5 kg
Gears: 11-36T on back, 46-30T on front. So min speed is 30/36 = 0.83 and max is 46/11 = 4.18, so range is 4.18 / 0.83 ~= 5. Compared to Kross which was 11-32 on back vs 48-28 on front, so min 28/32 = 0.875 and max 48/11 = 4.36. So the ranges are very comparable! This confirms Ciro's suspicion that 3 speeds on cranckset is just useless.
I was sized just at the lower limit of XL, but decided to go for it. The seatpost goes all the way into the tube, which is a good thing, might help with noises?
Frame serial under bottom bracket: WTU173C0374S. Registered at: www.bikeregister.com/
Initial impressions:
I'm unable to place a U-lock carrier on this bike in a way that doesn't block one of the two bottles inside frame, or hits leg on if on side. Tried both Kryptonite and Abus ones I have lying around. Shame. Also the Topeak MTS Trunkbag does not fit well on the pannier rack, it is not wide enough to strap: 11cm outer width, 9cm inner width, same geometry as that of the Liv bike.
Log:
2026-08-08: failed to unclip at slow speed, fell over, and broke derailleur hanger... I'm unable to unbolt the frame bot, hex is rounded off even though I never touched it I think. I might to need help for this... Buying:
2026-04-15: was hearing back wheel hit something periodically. First I separated the disk breaks with the tool but didn't solve. Then I noticed broken spoke, 9th clockwise from tube valve. I replaced it, but unfortunately spreading the disk break made me lose back breaks so I had to go into break fluid territory. Some conclusions: you can't do break fluid without the break pads and disk break in the break. This opens it up for contamination. The correct thing to do is to put a plastic protection on top of them. I spilled fluid on break at one point, it was horrible, I ended up changing the break pad which improved things a bit. Overall break felt slightly worse than before but passable.
2026-02-13: chain reched .7, changed it to new KMC X9. x9 9 speed chain 114 links. www.amazon.co.uk/dp/B07J38GX7L Started slipping like crazy on cassette when I pedaled hard, changed it to www.amazon.co.uk/dp/B073H3DST7 SHIMANO CS-HG400 9-speed cassette (11-36 teeth) which internet said was compatible and it seems to be. Didn't manage to remove it and needed help from bike shop as usual. After that it stopped slipping.
2025-09-30: kickstand broken while taking it on car. Proceeding to buy Bontrager Rear Mount Adjustable Kickstand www.trekbikes.com/gb/en_GB/equipment/bike-accessories/bike-kickstands/bontrager-rear-mount-adjustable-kickstand/p/36015/ 20 pounds + 4 delivery. The new kickstand is slightly different from the previous one, it is less slick looking, but perhaps a bit more sturdy, notably the little arm is shorter which might help prevent the previous failure mode. It came with 3 types of screws, but the two of correct diameter were a bit shorter or longer than the old ones so I just kept the old ones.
2025-09-13: chain reached 0.75, rebuying KMC X9. x9 9 speed chain 114 links. www.amazon.co.uk/dp/B07J38GX7L
2025-08: rear mudgard broke in the exact same way as last time, so I'm saying fuck this bullshit and I just fixed it up with some wire which will likely be more resistant than the shitty metal thing they had.
2025-06-26: I suddenly lost the ability to shift the front gear, cable seemed fine, upon inspection I noticed that the pedal could move sideways. Maybe linked to screeching sound that has been coming from that area for a while. As per www.youtube.com/watch?v=cPQyQnNdews leading to www.youtube.com/watch?v=QqBtB8Kyl2U this is a different system from the Kross one, two piece compression slotted rather than 3 piece. The side to side issue is mentioned precisely at: youtu.be/QqBtB8Kyl2U?t=357 Buying the standalone removal tool: www.amazon.co.uk/Professional-Extracto-Compatible-Hollowtech-Maintenance/dp/B0DP6QF11X Fixing it fixed the shift issue, but I noticed that the little plastic piece was broken. Also a few days later it became loose again during a ride, but thankfully I had the tool and put it back mid rid. TODO wanted to rebuy it but it's really hard to find... Going to try this one: www.bikeparts.co.uk/products/shimano-altus-fc-mt210-chainset-46-30-9-speed-black-170-mm-w-o-chainguard 175 mm and see if it comes with both arms. Bought it. has both arms. But I can't fit it, appears to be 1 or 2 mm short compared to the other cranck, the new arm does go on the old crank. There is a small rubber seal that is perhaps not too well inserted which might be to blame? Fuck my life! On the old one, it seems to be fully inserted into a tight hole. I didn't manage to insert the new one enough to make it fit, but if I remove it then it fits... just removing it for now then, how important could that be? Famous last words. Web says 12-14 nM torque on holding screws.
2025-06: rebuying 2x Shimano B05S brake pads, breaking is not too great and I don't want to repeat last year's episode of on-road failure. Will also be bleeding for the second time, God help me. The old pads weren't too bad, but I replaced them anyways. The bleeding was a failure and the brakes were too soft to be useful at the end, fuck. Went to two bike shops, both said bleeding not too bad, one said likely problem was contamination/friction issues. Tried cleaning rotors further, improved. Buying sandpaper and new rotors as well 2x SHIMANO SM-RT26 6-Bolt Disc Rotor and also got two more brake pads, totalling 3 new before I start putting them in with new rotor.
2025-04: rear shift cable snapped near shifter when going over a cattle grid, was already a bit off in the previous days after last adjust I then noticed. I'll buy a SHIMANO Gear Inner Wire Y60098070 on Amazon and might pass by bike shop as well I'll see.
2025-03: rear middle metal connection broke off read mudguard. Rebuying £21.04 from: www.tritoncycles.co.uk/frames-forks-c6/frame-fork-spares-c152/eurofender-snello-700c-fenders-46mm-rear-p33330/s93941 Quite disappointed with that, didn't come with any screws, though perhaps these are frame dependant. And the drilling was a bit different, this model seems to be intended to have some wiring passing inside via some rubber tubes that I removed, and unfortunately the hole on front was too high up and didn't match up with the screw hole on frame. I just removed the broken metal piece from it and put it on the old mudguard.
2024-09: buying CHUMXINY Brake Bleed Kit: www.amazon.co.uk/dp/B0CXDQ2S1S I hope I don't regret this. But I can't find an original one on Amazon either so... £12.74. Quality is a bit crap but seems to work. The 7mm wrench however is so bad that it can't unscrew a 7mm nut.
2024-09: chain reached 0.75, rebuying KMC X9. x9 9 speed chain 114 links: www.amazon.co.uk/dp/B07J38GX7L
2024-09: when going down a hill in intense breaking, noise started coming from back disk brake. Tried to adjust, but made it worse, had to bail out on nearby bike shop. Readjusted, told me to replace back pads and likely bleed. Bought two Shimano B05S brake pads to replace the B01S that came with the bike, Internet says compatible. Brake maintenance finally caught up with me, it was a great summer and I kept putting it off. Changed just the back one for now, front still has life it seems.
2024-06: noticed a sideways lump on back tyre between spoke 23 and 24 when washing. The only sign of damage was internal near grip part, I could see some clear shearing... God those tyres are crap, or at least crap to what I've subjected them. Inner tube and outside seem perfect, so weird. If only the Schawlbe had worked! But OK now I'm forced to get something new and better, thinking:They had a Schwalbe Marathon Plus 700x35c (non-Tour, as that one didn't fit as per previous experiment) on the shop and I went for it. They said 35c was the maximum recommended for that mudgard which is a bit of a shame, but good to know. Also getting one from Amazon to match on front as shop only had one.
2024-04: micropuncture on front tube? Could not identify during ride, refilled and was OK to get home. Almost no pressure in middle of ride. Passed through some deep water which may have made things worse? Had a small pice of glass-like material stuck in tyre, but didn't seem to penetrate? One day and a half later, was full empty again after full fill without riding, so confirming micropuncture theory. Buying 2x Conti Tube Cross 28 (700C) presta inner tubes.
Tried to put a spare Schwalbe Men's Marathon Plus Tour 700x40C on the bike to get better stability. It seemed to fit the wheel quite well, but unfortunately failed to go well in the fork because it was too tall and hit the mudgard. Without mudgard it might work. Measured height was 6cm for Schwalbe vs 5.3cm for the stock one.
2024-02: another broken spoke... what crappy weak wheels!!! Bought Bavel 290 mm spokes 36pcs 14G J Bend Silver. Broken position was 22nd clockwise from inner tube valve hole.
2023-12: chain reached 0.75, rebuying KMC X9. x9 9 speed chain 114 links.
2023-12: broken spoke! Also had to replace nipple because broke inside nipple. At least learned how to change tire at last.

Aluminium extractor filter for 208298104403
Hi there,
I'm trying to buy a spare aluminium extractor filter for an Elica extractor, but I can't find the right size on the website.
My 12NC is : 208298104403
My filter looks a lot like this: shop.elica.com/en/accessori/filtro-grassi-in-alluminio-cod-GRI0077330A.html but the dimensions are different: I measured 45.9cm x 17.6cm on my old one.
Do you have that for sale?
When I came, two Bell GU4 (MR11) 20W 12v.
One burnt. Put in an ASDA halogen one.
ASDA burnt, put in TopLux on right, old Bell left.
2019-01-24, right one burnt a few days ago, old Bell still works. Inner part black, and black dot on the wire. Putting new TopLux again, but this time on the left, old bell on right.
2019-01-24 toilet top lamp also burnt a few days ago, but not at the same time as mirror. Diall, 240V 40W, GU10. Putting in IKEA 240V 35W.

2019-03-28 toilet top lamp right burnt, IKEA 240V 35W GU10. Waiting for people to come to look at transformer, there is definitely something wrong.
2019-04-03 top lamps: replaced with LED (LAP GU10 3W) since lower power, transformer not changed. Mirror lamps: transformer changed, left one replaced with Homebase Halogen 20W 12V. When I came back lamps flickering badly and sometimes not turning on, recalled technician.
2019-04-12 mirror lamp: it was just he connector that was bad, it was changed, also put LEDs there to make it less warm and hopefully have less tear on connector.
Linux on SSH and bare metal blinker both work on this board, so the rest of the board seems alive.

The acid dissociation constant, often represented as \( K_a \), is a quantitative measure of the strength of an acid in solution. It describes the equilibrium position of the dissociation of a weak acid in water, indicating how well the acid donates protons (H⁺ ions) to the solution.
The Irving Langmuir Award is a prestigious honor given by the American Vacuum Society (AVS) to recognize outstanding achievements in the field of surface and vacuum science. Named after the American chemist and Nobel laureate Irving Langmuir, the award is intended to acknowledge significant contributions to the understanding of surfaces and their science, particularly those that pertain to vacuum technology.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
